Problems solved by technology

[0010] In practical applications, the above scheme has the following problems: low system reliability, poor link stability, additional hardware needs to be added, and link bandwidth utilization is only half of the actual system configuration
Since the two physical network boards are active and standby, only one of the physical network boards communicates with the service board at any time, and the link between the service board and the other physical network board does not work, so the link bandwidth utilization low rate

Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] The present invention actually applies the port binding technology to the internal interconnection of the communication equipment system based on Ethernet switching, and provides a complete internal interconnection solution. The physical block diagram of the internal interconnection of the communication equipment of the present invention is as follows: figure 2 As shown, the sub-frame switching network 1 and 2 refer to two physical network boards in a certain frame inside the communication device, which can be Layer 2 (MAC layer) or Layer 3 (IP layer) switching of FE or GE with a certain capacity. In practical application, it can be realized by a dedicated switching chip.

[0050] In the frame, the communication between the physical network boards of the...

Abstract

The present invention discloses an inner reliable interconnected communication apparatus. The present invention adopts port binding technology to realize communication apparatus reliable interconnecting, through port binding two mutual backed physical network board communications to form one logical network board. In-frame service boards are all bound with tow physical network boards for realizing in-frame communication, logical network among different frames are all interconnected; physical network board in same frame also is bound; on this basic, service board or network board capable of select port communication to realize service load equipartition in port; in port fault automatically abandoning said link to realize link level protection reversion.

Description

technical field [0001] The invention relates to communication equipment, in particular to the interconnection technology of individual boards inside the communication equipment. Background technique [0002] Communication systems are required to provide reliable and uninterrupted services to their users, especially in some important business applications, such as electronic money, order processing, customer service, inventory management, e-mail and Internet access, etc., business survivability becomes more important than ever, with availability requirements of 99.999% and beyond. Therefore, the network survivability has become an important factor affecting network design and construction, and the equipment used in the communication system needs to have high reliability accordingly. [0003] In this regard, a commonly used solution is redundant backup and active-standby switching technology. [0004] Redundant backup and active / standby switching technologies have various ba...
